To sum up, this release review corresponds to an improved version of the engine and UI parts, mainly for better flexibility and customization.

Release: 

0.3.0

Description: 

EMF Diff/Merge is a diff/merge tool for models. Its main purpose is to help build higher-level tools that need to merge models based on consistency rules. GUI components are also provided. Typical usages include model refactoring, iterative model transformations, bridges between models or modeling tools, collaborative modeling environments, or versioning systems.

This is the Luna release of EMF Diff/Merge. It provides better flexibility and customization facilities in order to cover a wider range of usages and integration scenarios.

API Certification: 

The project leadership certifies that the APIs in this release are "Eclipse Quality".

Architectural Issues: 

EMF Diff/Merge is made of two components:

  • A diff/merge engine. This component can be customized/extended via model scopes (what to compare), match and diff policies (how to compare) and merge policies (how to merge).
  • A GUI component which relies on the engine. This component provides an extension point which allows specifying engine customizations that are made available in the GUI.

In addition, each component comes with a simple customization for GMF scopes (diagrams and models) that illustrates the overall extendibility of the technology.

 

Security Issues: 

No security issue identified.

Non-Code Aspects: 

The complete EMF Diff/Merge documentation is available from the EMF Diff/Merge Wiki page:

 

Usability Details: 

EMF Diff/Merge intends to conform to the User Interface Guidelines.

End of Life: 

No EMF Diff/Merge component is deprecated so far.

Standards: 

EMF Diff/Merge does not implement any standard.

Communities: 

EMF Diff/Merge obtained the "Most innovative project/feature" award at EclipseCon World 2013. It is a young project whose usage is spreading.

The forum, bugzilla and Gerrit show activity by different people and organizations. In particular, several Gerrit pull requests have been submitted by people external to the project.

This release is part of Luna.
